CC3220SF builds on the CC3220S and integrates a user-dedicated 1MB of executable Flash, in addition to the 256KB of RAM.

Start your internet-of-things (IoT) design with a Wi-Fi CERTIFIED™ Wireless Microcontroller. The SimpleLink™ Wi-Fi® CC3220x device family is a system-on-chip (SoC) solution, that integrates two processors within a single-chip:

The application processor is an Arm® Cortex®-M4 MCU with a user-dedicated 256KB of RAM and an optional 1MB of serial flash.

The network processor MCU runs all Wi-Fi® and internet logical layers. This ROM-based subsystem includes an 802.11b/g/n radio, baseband, and MAC with a powerful crypto engine.

These devices introduce new features and capabilities that further simplify the connectivity of things to the internet. The main new features include the following:

Optimized low-power management

Enhanced networking security

Device identity and Asymmetric keys

Enhanced file system security (supported only by the CC3220S and CC3220SF variants)

IPv6 TCP/IP Stack

AP mode with support of four stations

Up to 16 concurrent BSD sockets, of which 6 are secure

HTTPS support

RESTful API support

The CC3220x device family is part of the SimpleLink™ MCU platform, a common, easy-to-use development environment based on a single core software development kit (SDK), rich tool set, reference designs and E2E™ community that supports Wi-Fi®, Bluetooth® low energy, Sub-1 GHz and host MCUs.
